The Halo Movie: Past, Present, and Future

GI - With the release of 343 Industries’ 4th installment in the series, Halo is once again at the center of the gaming universe. If the $220 million on opening day for Halo 4 is any indication, the franchise is going to be around in some form or another for many more years to come. After the success of the latest release and a rejuvenation of the series, one question still needs answering: Where’s the Halo movie?
(Culture, Halo)

The reason i feel that micrsoft havn't tried again is because a halo game makes way more money then a halo movie could unless it was as big as avatar or something while a movie would have higher cost of production and greater risk due to the fact that a halo game is sure to sell while a movie might not also a bad movie could impact badly on the overall quality associated with the franchise. If they are going to do the movie please get peter jackson to do it :)
